I negotiated with my agent that if they got my asking price or above I would pay them the full commission, if it was below then they had to knock 1% off. I set the asking price toward the high end of my estimate so they would have to work a little of their magic to get the price, but we both agreed it wasn't impossible and they accepted the terms. They could have turned it down.
But bottom line is, it is completely negotiable and don't settle for 6%. As long as you are fair most agents are willing to deal. In the end I sold my house for $2000 less then the asking price, I was happy.
Now I am looking for a house and what really annoys me is that many of the listing you see online have 1 or 2 line descriptions or none at all and the pictures are horrible (out of focus, weird angles, or bad quality). I also find errors like the house has a garage (in the picture) for example but when you search for houses with a garage the house doesn't show up because someone didn't take the time to enter all the information and check all the boxes properly. I see mistakes like this a lot and these people are making thousands of dollars when a home sells!
So interview several people, don't pick the first one and look at some of their listings online first to see how well they market their current customers.
In my post, where I indicate that an agent may quote you a range, I am referring to an individual agent's pricing range, not an industry standard. Some Realtors work within price and fee ranges, and other Realtors may have set fees, and that set fee for that Realtor or brokerage is perfectly legal.
I have heard consumers state, "but I was told that commissions are negotiable" when quoted a set fee by an agent, so that statement can cause confusion. A business may set a fee schedule for itself. Businesses may not price fix within an industry. Anti trust laws are not exclusive to the real estate industry.
A brokerage (company) or individual agent may establish their own fee schedule which might be firm. Many agents will negotiate the commission and fees based upon the property and the individual seller. In my post below, all reference to "ranges" refer to a discussion with an individual agent about their fee ranges, and not the industry.
If you were to phone a handful of agents and discuss the fees that each individually charged and services provided, you would have an idea of your options.
It will be challenging for RE Pros to answer this question on this forum. Anti-trust laws prohbit price fixing (in any service, trade or biz) and discussion on this forum might be construed as a violation of anti-trust. For legal compliance reasons, most Realtors will shy away from engaging in fee discussion on this fourm. Individually, many will be happy to discuss this with you by phone or direct email correspondence.
You will be able to find real estate agents who will represent you for as little as a few hundred dollars to fees in the 5 figure range, or more. There is usually a relationship between the amount of fees paid and the representation and marketing provided.
On the lower end of the fee scale is flat fee to the seller for minimal seller representation. In addition to the fee paid for seller representation, you will have commisison or compensation due to a buyers agent if you choose this route.
On the other end of the scale is full serive that would include a comprehensive marketing plan.
While most agents will probably provide an answer that it depends upon your property and your needs, you can ask them to provide you a range. It is true that if often depends upon the individual seller and the specific property.
Example: If I am going to do a video on your home, build a single property site, and place/promote this via several print ads, the fee structure that I quote may be much higher than if the marketing plan for your home does not include this. Every real estate agent sets their own fee structure under the guidelines of their brokerage firm.
When making your inquiries via phone, it may be helpful to loosely define the type of service and representation you seek. If one were to ask, "How much does a car cost?", one might get an answer that indicates a pre-owned economy car might cost a few thousand, and an exquisite luxury vehicle could run in the 6 figure range. In contrast, the question "What is the price range for a brand new 2008 luxury 4-door sedan loaded with bells and whistles?" would generate more specific data in response.
Good luck in the sale of your property.
